• Automatic MDIX support
• Supports transparent VLAN forwarding
• Packet length of up to 1536 bytes
• Fault propagation of line interface error conditions to Ethernet port (optional
feature)
• When filtering is enabled, there are two QoS levels via two priority queues to
handle priority, which is determined in the following order:
 If the packet received is an Ethernet tagged frame, product marks the
packet according to the tag priority (0–7).
 0–3: low priority queue
 4–7: high priority queue
 Otherwise, LRSI-F-27 marks the packet according to IP ToS priority (0–7).
 0–3: low priority queue
 4–7: high priority queue
 Untagged and non-IP frames enter the low priority queue
• Product frames egress from the queues with a 1:2 ratio, two frames from
high priority, one frame from low priority
• The products buffer holds 120 frames (of 64 bytes).
